Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Disconnect the negative terminal of the battery to ensure safety.
Allow the vehicle to cool if previously driven.

2. Inspect and Replace ABS Fuse

Locate the fuse box (refer to the owner’s manual for the exact location).
Remove the fuse for the ABS and inspect it visually.
If blown, replace it with a fuse of the same amperage rating.

3. Check ABS Wheel Speed Sensors

Identify the location of each wheel speed sensor.
Disconnect the sensor connectors and inspect for any physical damage.
Clean the sensor mounting area to remove any debris.
If damaged, replace the wheel speed sensor with a new one.

4. Inspect Wiring and Connectors

Trace the wiring from the ABS module to the wheel speed sensors.
Look for any signs of fraying or corrosion in the connectors.
Repair or replace any damaged wiring or connectors as necessary.

5. Test ABS Module

Reconnect the battery terminal.
Use a multimeter to check the voltage and ground at the ABS module.
If the module is not receiving power, further diagnose the wiring back to the fuse box.
If the module is faulty, replace it according to the manufacturer’s specifications.
